Over the years I've visited hundreds of galleries and I've come to understand what makes an exhibition work. The curator's choices (what to display, how to arrange it, and the theme that ties it together) shape every visitor's experience. In these reviews, I look at how well each exhibition comes across, what the curators set out to say, and what they may have left out. Whether you love art, are curious about what happens behind the scenes, or simply want ideas for things to do in London, I hope you'll follow along.
